FOUNTAIN-PEN.

SHEQIFICATIQN formingpart of Letters Patent No. 709,307, dated September16, 1902.

Application filed June 26. 1902. Serial No. 113,269. (No model.)

. nosha, in the county of Kenosha and State of Wisconsin, have inventedcertain new and useful Improvements in Fountain-Peus; and

I do declare the following to be a full, clear, and exact description ofthe invention, such I as will enable others skilled in the art to whichp 3, which receives the capillary tube 4, exteit appertains to make anduse the same.

This inventionrelates to fountain-pens of the stylographic type,designedas an im prove ment upon the fountain-pen shown and described in myLetters PatentNo. 699,499, dated May 6, 1902, whereby, first, provisionis made for varying the density of the hygroscopic or absorbent materialto regulate the flow of ink through the pen-point; second, provision ismade for removing the capillary tube, whereby the barrel of the pen maybe filled by injection in the usual manner, and, third, provision ismade for the removal of thetubular pen-point, whereby when it becomesworn or damaged it may be replaced with a new or perfect one.

With these objects in view the invention consistsof certain novelfeatures of construction, combination, and arrangement of parts, whichwill be hereinafter more fully described, and particularly pointed outin the appended claims.

In the accompanying drawings, Figure 1 is a perspectiveview of thestylographicpen, illustrating the pen-point closed by the usual cap.Fig. 2 is a longitudinal sectional view through the pen, showing the capslipped over the upper end thereof. Fig. 3 is a view showing inperspective, on an enlarged scale, the several parts constituting thepen; and Fig.

'4 is a fragmentary view of the tip of the pen- In the drawings, 1denotes the barrel or reservoir of the pen, the upper end of which isformed with a capillary chamber 2, termihating in aninteriorly-screw-threaded neck riorly screw-threaded to engage said neckand provided with a head 5, which when the tube is screwed firmly homeengages theend of the neck and forms a complete air-tight closure. Theopposite end of the barrel is screw-threaded, as at 6, and is formedwith atubular extension 7.

8 denotes the tubular pen-point, the lower end of which is conical andis formed on one side with a flat surface 9, which has a feedaperi ure10, preferably oblongin outline and having its walls leading to ornearly to the extreme tip of the pen-poin The opposite end of thetubular pen-point is provided with an annular shoulder 11. .Thepen-point is slipped over the end of the extension 7, and aninteriorly-threaded coupling-sleeve 12 is slipped over the pen-point andengages the shoulder 11 and has its threaded portion engaged with thethreaded portion Got the barrel., Located within the pen-point anddesigned to check the flow of ink through the feed-opening therein is ahygroscopic or absorbent agent, preferably consisting of raw cotton.This material is confined between the tip of the pen-point and the lowerend of the extension, and by adjusting the sleeve 12 it may be.compressed to increase its density, and thereby check or regulate theflow ofink through the feed-opening in the pen-point. The pen-point ispreferably made of glass, and the other parts described are preferablymade of hard rubber, but may be made of any suitable well-known ordesired material. To prevent the escape of ink between the penpoint andthe extension, the extension may be provided with a packing of cork orother suitable material, (indicated by the numeral 13.)

14 denotes a cap which when the pen is not in use may be engaged withthe pen-point and when the pen is in use may be engaged with the neck 3and head 4, as shown in Fig. 2. This cap is provided with the usualventopening 15.

As the operation of the pen is substantially the same as that describedin the patent here inbefore referred to, it is not thought necessary torepeat the operation herein.

The construction admits of theexpeditious assemblage and disassemblageof parts for the purpose of renewal, repair, orcleansing. By providing aremovable pen-point when the same becomes worn or damaged it may bereplaced with a new one. By providing means for varying the density ofthe absorbcut or hygroscopic material the flow of ink through thepen-point may be regulated to a,

Various changes in the form, proportion,

and details of construction maybe made Withinthe scope of the inventionWithout departing from the spirit or sacrificing any of the advantagesthereof.

Having thus described my invention, What I claim, anddesire to secure byLetters Patcut, is 1 v 1. In a pen of the character described, thecombination with a barrel or reservoir and a pen-point, of an absorbentmaterial arranged to retard the flow of ink from one to the other, andmeans for varying the density of said material, for the purpose ofregulating the flow of ink, substantially as set forth.

2. In a pen of the character described, the

. combination with a barrel or reservoir, of a tubular pen-pointcommunicating therewith,

absorbent material located therein to retard the flow of ink, and meansto vary the density of said material, substantially as set forth.

3. In a pen ofvthe character described, the combination with a barrel orreservoir, of a tubular pen-point, absorbent material located therein, atubular extension projecting from the barrel into the pen-point, andmeans for sliding the pen-point upon the tubular exten- 1 sion to varythe density of the absorbent material within the pen-point,substantially as set forth. 7

4. In a pen of the character described, the combination with a barrel orreservoir, of a tubular pen-point, absorbent material locatedtherein,-a'tubular extension projecting from the barrel into thepen-point, and means for sliding the pen-point upon the tubularextension to vary the density of the absorbent material within thepen-point, said means consisting of a couplingrsleeve loosely connectedto the pen-point and having a screw-threaded connection with the barrelor reservoir, substantially as set forth.

5. In a penof the character described, the combination with an open'-ended barrel or reservoir, of a capillary-tube removably connectedwith one end of the barrel or reservoir and open at each end,substantially as set forth.

6. In a pen of the character described, the

combination with an open-ended barrel or reservoir provided with ascrew-threaded neck, of a capillary tube open at each end and providedwith a screwthreaded head to engage the neck, substantially as setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
